uint8	sin_zero [8]

Detailed Description

Socket address structure for IPV4 addresses. Used to specify socket address information to which to connect to. Can be cast to sockaddr structure.

Field Documentation

sin_family

uint16 sin_family

Specifies the address family(AF). Members of AF_INET address family are IPv4 addresses. Hence,the only supported value for this is AF_INET.

sin_port

uint16 sin_port

Port number of the socket. Network sockets are identified by a pair of IP addresses and port number. It must be set in the Network Byte Order format , _htons (e.g. _htons(80)). Can NOT have zero value.

sin_addr

in_addr sin_addr

IP Address of the socket. The IP address is of type in_addr structure. Can be set to "0" to accept any IP address for server operation. non zero otherwise.

sin_zero

uint8 sin_zero[8]

Padding to make structure the same size as sockaddr.
